Title SOME RESULTS OF JENSEN’S INEQUALITY FOR A BUNCH OF SPECIAL FUNCTIONS Type Presentation Keywords Jensen’s inequality; tgs-convex function; Global bounds Abstract In this article, we describe some features of tgs-convex functions along with examples. Then we examine the non-positive property of tgs-convex functions. We obtain a natural type of Jensen’s inequality for convex tgs-functions Researchers Sayyed Mehrab Ramezani (First researcher)hasan barsam (Second researcher)
